The mean (±se) overall proportion correct on the NaCl vs. KCl discrimination task collapsed across all NaCl and KCl trials on last 6 test sessions without amiloride treatment during weeks 5 and 6 of postsurgical testing. The different symbols represent the performance of individual rats and are consistent within a specified group across all figures. Some rats in all groups that were impaired during the earlier sessions of postsurgical testing improved their performance over the 6 weeks of postsurgical testing suggesting that they were able to “relearn” the discrimination based on the input remaining in the intact gustatory nerves. See Figure 1 caption for definition of group abbreviations.
